摘要
正确判断焦炭成熟度对提高焦炭质量和降低炼焦耗热量十分重要,而采用结焦指数模型可定量判断焦炭成熟度。通过测定粗煤气温度的6种方法和试验数据,获得结焦指数模型CI=τC/τmax(炭化时间/火落时间)。同时根据不同炉型和结焦时间找出最佳CI值,并用于焦炉加热优化串级调控工艺(OCC)。
Correct judging of maturity of cokes is important to improve the coke quality and lower heat consumption in coking process.The model for coking index can be used quantitatively to judge the coke maturity.Coking index CI=τC/ τmax(carbonization time/fire falling time) is achieved by means of the raw gas temperature measured with six different methods as well as the experimental data.The optimum CI value is determined according to the characteristics of different coke oven type as well as coking time.And it is...
